It was narrated that 'Aishah said:

"I would drink when I was menstruating, then I would hand it to the Prophet (ﷺ), and he would put his mouth where mine had been and drink. And I would nibble at a bone on which some bits of meat were left when I was menstruating, then I would give it to the Prophet (ﷺ) and he would put his mouth where my mouth had been."

أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا مِسْعَرٌ، وَسُفْيَانُ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَشْرَبُ مِنَ الْقَدَحِ وَأَنَا حَائِضٌ، فَأُنَاوِلُهُ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ فَيَشْرَبُ مِنْهُ وَأَتَعَرَّقُ مِنَ الْعَرْقِ وَأَنَا حَائِضٌ فَأُنَاوِلُهُ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ ‏.‏
